LIGHTNING-ROD.

SPECIFICATION forming part of Letters Patent No. 667,366, dated February5, 1901.

Application filed May 22, 1900.

T0 ctZZ whom it may concern:

Be it known that I, EBBE J. HANSEN, a citizen of the United States,residing at Atlantic, in the county of Cass and State of Iowa, haveinvented certain new and useful Improvements in Lightning-Rods; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to improvements'in lightning-rods and electricconductors; and the objects of my improvements are, first, to givespring-support to the rod when placed upon buildings or other structuresand to spring back into position if disturbed on the building; second,to cause the rod to roll straight from the spool on which the rod may bewound for the purpose of shipping, thereby preventing kinking of the rodwhen unwound; third, to facilitate fastening the rod aroundcorners,eaves,chimneys,and other angular parts of the building orstructures to which the rod may be applied, and, fourth, to provide acentral support for the rod, which increases the conductivity anddurability of the rod over lightning-rods and electric conductors nowinuse, as it is the inside of a copper lightning-rod cable that gives awayfirst on account of corrosion where the same consists of fine wire, myimprovements adding one great advantage in that the center consists of aheavy tempered copper or brass wire, which will delay the decay causedby the weather and other means of corrosion. I at tain these objects bythe construction illustrated in the accompanying drawings, in whichFigure 1 is the central spring, around which ropes or clusters are woundor twisted. Fig. 2 is a cluster or rope of small wires twisted together,and Fig. 3 is a section of the finished or completed rod or conductor.

Similar letters refer to like parts throughout the several views.

The letter A designates the central springrod, of copper or brass. I

B refers to a cluster or rope of soft small copper wires wound ortwisted together. 0 C O 0 indicate the individual small copper wireswhich make up or compose one of the ropes or clusters 13. A suitablenumber of these ropes or clusters B having been first prepared they arelaid in juxtaposition about and around the spring central red A, and theSerial No. 17,579. (No model.)

said ropes or clusters B are then twisted or spirally wound upon andabout the central spring-rod A, of copper or brass, which spring centralrod is shown in the diiferent views of the drawings and is larger thanthe individual soft small copper wires composing the ropes or clusters13.

I may select any suitable-sized wire for the central spring core orsupport, but prefer wire N0. 9, and various sizes of small copper wirescomposing the ropes or clusters may be chosen with good effect.

I have in the drawings illustrated four small soft-copper wirescomposing one of the ropes or clusters B,yet I may use less number ofsuch small copper wires for the ropes or clusters. One of said ropes orclusters consists of six copper wires and another rope or cluster isprovided with seven wires, and yet I may make my ropes or clusters ofless than four or more than seven of said wires.

I have shown upon the drawings six ropes or clusters wound spirallyaround or twisted about the spring central core; but it is manifest thatI may select more than six or less than six such ropesor clusters incarrying out my invention.

I do not desire to confine my invention to the precise number of wiresshown and herein described composing the ropes or clusters; neither do Idesire to confine my invention to the exact number of ropes or clustersspirally wound or laid about the central core or support of springmetal; but

What I claim as my invention, and desire to secure by Letters Patent,is-

1. A lightning-rod consisting of the heavy central spring-core support,copper wires twisted together upon themselves into ropes, said ropeslaid' in juxtaposition upon said tempered spring central core-support,and spirally wound or twisted thereon.

2. A lightning-rod consisting of a core of spring-wire of goodconductivity, ropes or clusters of copper wire twisted together uponthemselves, and the said ropes or clusters spirally wound or twistedupon the said spring-core.

In testimony whereof I have hereunto affixed my signature in presence oftwo witnesses.
